CHURN.

SPECIFICATION formingpart of Letters Patent No. 657,805, dated September11, 1900.

Application filed January 17, 1900. Serial No. 1,748. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES EMRY YATES, a citizen of the United States,residing near Mill Grove, in the county of Mercer and State of Missouri,have invented a new and Improved Operating Mechanism for Churn- Dashers,of which the following is afull, clear, and exact description.

My invention relates to mechanism for operating churn-dashers.

The object of my invention is to provide a comparatively simple andefficient mechanism of the above-indicated class which may be readilyconnected with and disconnected from the dasher of an ordinary churn andwhich may be operated uniformly with small expenditure of power.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of the churn com'plete. Fig. 2 is an endelevation thereof. Fig. 3 is a side elevation with parts in sectionsubstantially on the line 3 3 of Fig. 2, and Fig. 4 is a sectional planview on the line 4 4 of Fig. 3.

A is the churn-body, which may be of any suitable construction and restsupon the base B of the machine.

The cover 0 is preferably provided with a funnel D, surrounding the rodE of the dasher F and intended to prevent splashing of the milk. Thedasher-rod E is provided at regular intervals with apertures E, adaptedto be engaged by pins G, secured to a U-shaped cross-head G, which hassleeves G arranged to slide on a stationary vertical guide H, secured tothe post I. The upper member of the cross-head G is provided with ahorizontally-disposed loop G (see Figs. 1 and 4,) through which extendsa pitman or connecting-rod J ,connected with the cross-head at J andoperated by a crank K upon a shaft L, journaled in the post I. Thisshaft L carries a fly-wheel M and a pulley N, which is driven by meansof a transmission-cord 0 from a large pulley P upon the actuating-shaftQ. This shaft is also journaled in the post I, and preferably the end ofthe shaft also has a bearing in the guide H, said guide having an upwardextension or bracket H, in which is formed an additional bearing for theshaft L. The shaft Q is provided with a crank-handle R, so as to beadapted to be operated by hand. The post I is braced laterally by twoinclined or diagonal stays S, extending from the bottom of the guide Hto side extensions 1 of the post, and, furthermore, a rear brace T isprovided, secured to the base B and to the post 1, preferably as shownin Fig. 2, by means of the same bolt U which also secures the stays Sand the lower end of the guide H to the said post.

The machine is operated by turning the crank R, which causes thecross-head G, and with it the dasher F, to reciprocate up and down,churning the milk in the ordinary way. It will be observed that thedasher-rod is held very securely, since it is fastened to the crossheadG at two points of its length, and to absolutely prevent any possibledisengagement of the dasher-rod from the cross-head a suitable pin V maybe passed through apertures provided in the ends of the pins G. It willbe understood that the said pins are passed through two of the.apertures E and that the distance between the dasher F and thecross-head G may be varied by engaging the pins G through appropriateapertures E, so that the machine may be used in connection with churnbodies of different sizes. The motion of the cross-head G also is verysteady, owing to its being guided by two sleeves or slides G and owingto its being securely fastened to the dasher-rod. The employment of thefly-Wheel M and the particular bracing of the post I also contribute torender the motion steady and uniform.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In an operating mechanism for churns, thecombination of the stationary guide, the cross-head mounted to move onsaid guide and provided with projections adapted to be connected to adasher-rod and with a loop extending transversely in relation totheguide, the pitinan connected with the cross-head and extending throughsaid loop, and crank mechanism connected with the pitman.

In an operating mechanism for churns, the combination of thestationary guide, the cross-head having two spaced slides mounted tomove on said guide and provided with two In testimony whereof I havesigned 1113* projections adapted to be connected to a name to thisspecification in the presence of IO dasher-rod and with a loop extendingtrans two subscribing Witnesses.
